Thanks. ---8<--- In preparation of adding new ECDSA self-tests, the existing data is moved to a separate file. We only need to compile this file in if CRYPTO_RSA is configured. The old fips_signature_selftest is no longer an init function, but now a helper function called from fips_signature_selftest_rsa.

MIME-Version: 1.0 Commit c27b2d2012e1 ("crypto: testmgr - allow ecdsa-nist-p256 and -p384 in FIPS mode") enabled support for ECDSA in crypto/testmgr.c. The PKCS#7 signature verification API builds upon the KCAPI primitives to perform its high-level operations. Therefore, this change in testmgr.c also allows ECDSA to be used by the PKCS#7 signature verification API (in FIPS mode). However, from a FIPS perspective, the PKCS#7 signature verification API is a distinct "service" from the KCAPI primitives. This is because the PKCS#7 API performs a "full" signature verification, which consists of both hashing the data to be verified, and the public key operation. On the other hand, the KCAPI primitive does not perform this hashing step - it accepts pre-hashed data from the caller and only performs the public key operation. For this reason, the ECDSA self-tests in crypto/testmgr.c are not sufficient to cover ECDSA signature verification offered by the PKCS#7 API. This is reflected by the self-test already present in this file for RSA PKCS#1 v1.5 signature verification. The solution is simply to add a second self-test here for ECDSA. P-256 with SHA-256 hashing was chosen as those parameters should remain FIPS-approved for the foreseeable future, while keeping the performance impact to a minimum. The ECDSA certificate and PKCS#7 signed data was generated using OpenSSL. The input data is identical to the input data for the existing RSA self-test.
